Measurement of the $^{235}$U(n,f) cross section relative to the $^{10}$B(n,α) reaction with Micromegas detectors at the CERN n_TOF facility: First results / n_TOF Collaboration
Neutron cross section measurements are often made relative to a neutron cross section standard. Thus, the accuracy of the neutron standards determines the best possible accuracy of the neutron measurements. [...]

Measurement of the $^{14}$N(n,p)$^{14}$C cross section at the CERN n_TOF facility from sub-thermal energy to 800 keV / n_TOF Collaboration
Background: The $^{14}$N(n,p)$^{14}$C reaction is of interest in neutron capture therapy, where nitrogen-related dose is the main component due to low-energy neutrons, and in astrophysics, where 14N acts as a neutron poison in the s-process. Several discrepancies remain between the existing data obtained in partial energy ranges: thermal energy, keV region and resonance region. [...]

Development of an Ionization Chamber for the Measurement of the$^{16}$ O(n, ${\alpha }$ )$^{13}$ C Cross-Section at the CERN n_TOF Facility / Urlass, Sebastian (TU, Dresden (main) ; HZDR, Dresden ; CERN) ; Junghans, Arnd R (HZDR, Dresden ; CERN) ; Hartmann, Andreas (HZDR, Dresden) ; Mingrone, Federica (CERN) ; Sobiella, Manfred (HZDR, Dresden) ; Stach, Daniel (HZDR, Dresden) ; Tassan-Got, Laurent (CERN) ; Weinberger, David (HZDR, Dresden) /n_TOF Collaboration
The$^{16}$ O(n,  ${\alpha }$ )$^{13}$ C reaction, as the inverse reaction of the astrophysically important$^{13}$ C( ${\alpha }$ , n)$^{16}$ O reaction, is proposed to be measured at the neutron time-of-flight (n_TOF) facility of CERN. To this purpose, a Double Frisch Grid Ionization Chamber (DFGIC) containing the oxygen atoms as a component in the counting gas has been developed and a prototype was constructed at Helmholtz-Zentrum Dresden-Rossendorf(HZDR), in Germany. [...]

Data for the s Process from n_TOF / n_TOF Collaboration
A considerable amount of (n, $\gamma $ ) reactions has been studied, so far, at the neutron time-of-flight facility n_TOF at CERN. The experimental program aims at determining and improving cross sections for a number of isotopes relevant to s-process nucleosynthesis. [...]

Measurement of the $^{16}$O(n, α)$^{13}$C cross-section using a Double Frisch Grid Ionization Chamber / n_TOF Collaboration
The $^{16}$O(n, α)$^{13}$C reaction was proposed to be measured at the neutron time-of-flight (n_TOF) facility of CERN. To this purpose, a Double Frisch Grid Ionization Chamber (DFGIC) containing the oxygen atoms as a component in the counting gas coupled with a switch device in order to prevent the charge collection from the so-called γ-flash has been developed at Helmholtz-Zentrum Dresden-Rossendorf (HZDR), in Germany. The first $^{16}$O(n, α)$^{13}$C measurement without seeing the charge of the γ-flash at n_TOF has been performed in November 2018. [...]

First Results of the $^{140}$Ce(n,$\gamma$)$^{141}$Ce Cross-Section Measurement at n_TOF / n_TOF Collaboration
An accurate measurement of the $^{140}$Ce(n,$\gamma$) energy-dependent cross-section was performed at the n_TOF facility at CERN. This cross-section is of great importance because it represents a bottleneck for the s-process nucleosynthesis and determines to a large extent the cerium abundance in stars. [...]

Gating of charge sensitive preamplifiers for the use at pulsed radiation sources / Urlass, Sebastian (HZDR, Dresden ; CERN ; TU, Dresden) ; Junghans, Arnd (HZDR, Dresden ; CERN) ; Mingrone, Federica (CERN ; Nat. Tech. U., Athens) ; Peronnard, Paul (CERN) ; Stach, Daniel (HZDR, Dresden) ; Tassan-Got, Laurent (CNRS/IN2P3 IJCLab ; CERN ; Nat. Tech. U., Athens) ; Weinberger, David (HZDR, Dresden) /n_TOF Collaboration
The development of a switch circuit to gate charge sensitive preamplifiers for use at pulsed radiation sources will be presented. This development was used for the $^{16}$O(n,$\alpha$)$^{13}$C reaction measurement with a Double Frisch Grid Ionization Chamber (DFGIC) at the neutron time-of-flight facility CERN n_TOF in Geneva, Switzerland.
